Mailmessage message = new mailmessage()

A classic!

MailMessage is a class in the.NET Framework that represents an email message. It's used to create and manipulate email messages that can be sent using the SmtpClient class.

When you create a new instance of MailMessage like this:

MailMessage message = new MailMessage();

You're creating an empty email message object. This object has several properties and methods that allow you to set various attributes of the email message, such as:

• Subject: the subject line of the email
• Body: the body of the email (text or HTML)
• From: the sender's email address
• To: the recipient's email address
• CC: the carbon copy recipients' email addresses
• Bcc: the blind carbon copy recipients' email addresses
• Attachments: an array of file attachments to be sent with the email

You can then set these properties and add attachments using various methods, such as:

message.Subject = "Hello World";
message.Body = "This is a test email";
message.From = new MailAddress("[email protected]");
message.To.Add(new MailAddress("[email protected]"));
message.Attachments.Add(new Attachment("path/to/file.txt"));

Once you've set up the email message, you can use the SmtpClient class to send it to the recipient's email server.

Here's a simple example:

SmtpClient client = new SmtpClient();
client.Send(message);

Of course, this is just a basic example, and you'll likely need to add more configuration and error handling depending on your specific use case.
